"We want to go out with the four founding members of Motley Crue and go out on top," said lead singer Vince Neil.

"We want to leave a legacy," added guitarist Nikki Sixx. "We want to have some dignity."

The band members have signed a legal agreement promising not to perform as Motley Crue after 2015.

A Motley Crue country tribute album is in the works, as is a big-screen version of the band's 2002 book, "The Dirt."
